I have a 2002 40 HP Mercury on my 13 footer. The person I bought it from suggests that I run it with oil and fuel. However, from what I can tell the engine already mixes the oil and fuel since there is an oil tank in it.
This is my engine model. https://www.crowleymarine.com/mercury-outboard/3021.cfm?mdl=9XNQCV
If you really want to be safe, forget about the oil injection system and add oil to each tank full at a 50:1 ratio. Be sure the oil tank is empty.
If you TRY the oil system and it doesn't work, you'll destroy the engine the first time out.
The engine is almost 20 years old and the injection systems weren't 100% reliable even back in the day. That said, some will advise you differently. Are ya feelin lucky?
Just want to make sure we are all on the same page here.
He is already running Pre-Mix fuel/oil.
To check to see if the VRO is working, fill the VRO Oil Tank.
If the oil level goes down then the VRO is working.
Then, and only then, can he use straight fuel.
The above should be performed after any disconnection of VRO lines, tanks, pumps, etc.
You should always run pre-mix first to test out any new repairs of the VRO system.
Yes, as Mark says, it may smoke during the test and may also foul the plugs.
